Ubuntu 18.04LTS 更新映象配置

清華大學開源映象站:
https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/

Ubuntu 的軟體源配置檔案是 /etc/apt/sources.list。將系統自帶的該檔案做個備份,將該檔案替換為下面內容,即可使用 TUNA 的軟體源映象。
備份:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
修改配置(見sources.list內容):
sudo gedit /etc/apt/sources.list
更新源
sudo apt-get update
執行結果如下:
